The Esplanade has two parts - a landscaped path under construction to connect John Goulter Drive with the historic Abbeville Estate function and wedding venue and the newly completed walking art trail around the lake, which has a peninsula with purpose-built seating in the centre.

Alexander said the new park was a privately owned public open space, created next door to Butterfly Creek, and a mountain biking track has been created next door.

"No ratepayer or taxpayer money went into this," he said.

The airport company commissioned 10 sculptures, including one by Terry Stringer, for the park around a small lake.

The airport is calling the new area an art walk. More art installations are being placed in other airport areas such as the terminal entry roundabout and in the Landing precinct.

Alexander said the aim was to link parts of the airport. Although the park is about 1km from the international and domestic terminals, visitors still walked over there to relax.
